Can keratins get into hair or do they just coat the surface?
• A. If hair is in perfect condition then Replicine keratins will deposit on the surface and form a sacrificial shield, protecting the hair from damage. However, if hair is damaged then the hair structure is opened up and Replicine keratins penetrate into the fibre and bind to the internal structure, rebuilding the damaged proteins to restore strength and condition to the fibre. Hydrolyzed keratins cannot bind in the same way to the hair as they do not have the structure required. We have studied the penetration of Replicine keratins into the hair structure using microscopy to prove that they penetrate and stay bound inside the hair.
